We look at the division of 39385598 by 386 
The aim is to understand the frequency of 386 in 39385598.

Step 1:
3 divided by 386 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 386

Moving on to step 2:
386 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 386

Moving on to step 3:
When dividing 393 by 386, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 7 after subtracting 386 from 393.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 386

On to step 4:
386 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 78, we end up with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 386

Moving on to step 5:
386 goes into 785 2 times with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 772 from 785 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 386

Let's proceed to step 6:
When dividing 135 by 386, we get 0 with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 1020.0
If we take 0 away from 135, we end up with 135.
Take the next digit (9) from the dividend and append it to 135, then repeat: 1359 / 386

Going ahead to step 7:
When dividing 1359 by 386, we get 3 with a remainder of 201.
The next digit of our result is 3. 
Result so far: 10203.0
Subtract 1158 from 1359 to get 201.
Bring next digit (8) of the dividend behind the 201 and repeat the process: 2018 / 386

Let's proceed to step 8:
2018 divided by 386 is 5 with a remainder of 88.
Put 5 as the next digit of the answer. 
Result so far: 102035.0
Subtracting 1930 from 2018 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
If we divide 880 by 386, we get 2 and a remainder of 108.
The next digit of our result is 2. 
Result so far: 102035.2
Subtracting 772 from 880 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
If we divide 1080 by 386, we get 2 and a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 102035.22
If we subtract 772 from 1080, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The quotient of the division is 102035.22, and the remainder is 0.308.
